Initial Examination and History

The first step in diagnosing swollen lymph nodes involves a thorough medical history and physical examination. Doctors will ask about symptoms such as fever, night sweats, and weight loss and check for node size, consistency, and tenderness. These initial assessments help narrow down potential causes and guide further testing.

Laboratory Tests and Imaging

If needed, doctors may order lab tests like a complete blood count or tests for infections such as HIV or tuberculosis. Imaging tests like ultrasound or CT scans can offer a more detailed look at the lymph nodes. These tests help differentiate between benign and potentially malignant causes of lymphadenopathy.
Swollen lymph nodes, also known as lymphadenopathy, can be caused by infections, immune responses, or malignancies. Diagnosis involves a medical history, physical examination, and possibly laboratory tests and imaging.

When Biopsy is Necessary

A biopsy may be required if the cause of lymphadenopathy remains unclear. There are several types of biopsies, including fine-needle aspiration and open biopsy. These procedures help provide a definitive diagnosis by allowing a detailed examination of lymph node tissue.
